Can rain blow in through the louvres? I sometimes get gale-force winds where I live.

Cool! How long does the battery last?

I have pulled the LEDs off the arduino to make the battery last longer. At the moment it has been running for 8 weeks, and the battery voltage is down to 90%. Given this, I am expecting that it sould last for 20+ weeks.

That's awesome! Maybe a rechargeable battery and a solar panel could provide even longer battery life?
I was expecting days, but months is very interesting.
How about more info on the electronics?

The hardware follows the instructions on the MySensors web site. http://www.mysensors.org/

The forum post for this project http://forum.mysensors.org/topic/1080/mini-weather-station

To make it last longer on a 9v battery I removed the LEDS from the arduino.

The sensors are connected:
BMP085 Pressure & Temperatue Sensor
SCL to A5 (analog input)
SDA to A4 (analog input)

DHT22 Humidity & Temperature Sensor
out (middle) to Digital pin 3

Battery level
A0 to Battery level input
100K to Gnd
1M to Battery

Excellent! Thank you so much :)
